Aggregate holding hopper, concrete stirring station and aggregate distributing control method

Abstract

The invention discloses an aggregate holding hopper, a concrete stirring station and an aggregate distributing control method. The aggregate holding hopper comprises a hopper body and a hopper valve, the hopper valve is arranged at the lower end of the hopper body, and the hopper is inside provided with a material discharge channel; and the aggregate holding hopper also comprises a material distributing device arranged on the hopper body; and the material distributing device comprises a revolving door mechanism and a driving mechanism, the driving mechanism is used to drive the revolving door mechanism to switch the close state and the open state, the close state of the revolving door mechanism is a state that the material discharge channel is closed, and the open state of the revolving door mechanism is a state that the material discharge channel is opened. The provided aggregate holding hopper is capable of realizing batch-wise pouring of two materials, avoids overlarge stirring resistance in a main machine, and improves the stirring efficiency and the stirring effect.

Description

technical field [0001] The invention relates to the field of mixing, in particular to an aggregate waiting hopper, a concrete mixing station and an aggregate distribution control method. Background technique [0002] The aggregate storage hopper is an important part of the mixing plant, which is used to store aggregate (including sand and stone) and feed on demand. The aggregate storage hopper stores the aggregates conveyed from the inclined belt, which saves the conveying time and is a necessary condition to ensure the production efficiency of the mixing plant. At present, the aggregate hopper structure of the general concrete mixing plant can be as follows: figure 1 As shown, the bottom is the bucket valve 1', the top is the bucket body 3' and the bucket cover 4' of the aggregate bucket, and the outside of the bucket body 3' is provided with a bracket 2'. Aggregate is conveyed by the inclined belt (not shown in the figure) and enters the bucket body 3' through port a, an...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned existing aggregate hoppers have the following problems: because the sand and gravel materials, water and cement are put into the mixer at the same time, the instantaneous mixing pressure of the mixing host increases sharply, and the stirring resistance is very large. Sometimes the current of the host is as high as 100A, which consumes a lot of energy, and It is easy to cause uneven mixing, lead to unqualified concrete quality, and cause the mixing shaft of the main engine to clog
